All-Copper Sun-strip

1. The tubes are forge self-melt welded to the fins and there are no solder, adhesive or mechanical joints.

2. The joint intensity will not deteriorate and craze with age or high temperature. 

3.The copper welding sew, whose breadth is 20 times as the fins-thickness, keep the  to the working-matter successive.

4. The copper rise-tube can be welded straightly to the collector tube. The welding process is simple with high intensity if welding-sews and without risk of leakage.

5.Used to Manufacture full-copper collector absorber, flat-plate collecor, efficient heat-pipe used in solar energy and kinds of efficient radiators, etc.
